It was never of God. Christianity began with Jesus. Catholics don't even use the KJV Bible. They have their own made up doctrine full of lies.
Acts 11:26 And when he had found him, he brought him unto Antioch. And it came to pass, that a whole year they assembled themselves with the church, and taught much people. And the disciples were called Christians first in Antioch.
All those different religion were started because people did not agree with God's laws. God told us not be be divided in our worshiping of him, yet here we have all those different religions.
1 Corinthians 1:10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
Not one religion today can agree on anything that is supposed to be the Word of God.
